Abstract (en)
A display device includes: a base substrate; a light emitting element located on the base substrate; a thin-film encapsulation layer located on the light emitting element; touch electrodes located on the thin-film encapsulation layer, each of the touch electrode including an opening; and a strain gauge including: resistance lines located in the openings, respectively, the resistance lines located in the same layer as the touch electrodes and having variable resistance values changed in response to a touch input; a first connection line connecting two resistance lines neighboring each other along a first direction; and a second connection line connecting two resistance lines neighboring each other along a second direction, the second direction intersecting the first direction, wherein the first connection line and the second connection line are located between the thin-film encapsulation layer and the resistance lines.
